Patent CA-2046305-A1 (CA)
Inventor: GRIBBLE MEIRION
IPC: B29C48/07
Filed: 1990-02-02
Abstract: A powdered mineral material is thoroughly mixed with a minor proportion of a thermosetting resin material followed by mixing the resulting dough with glass fibre reinforcement. A batch of the resulting formulation is extruded through a rectangular section die to form an extrudate of predetermined length. Several of these lengths are simultaneously pressed in a stack, one above the other, each extrudate between a pair of planar plates, one of which is a cast metal body which has been cast in material bearing an impression of the textured finished building product. The plates are thermostatically heated, at a temperature such that the extruded formulation can be thermally deformed and cured. The resulting mineral-filled resin product is typically a roofing panel.

Patent CA-2060729-A1 (CA)
Inventor: O'BRIEN STEPHEN E
IPC: G01N30/06
Filed: 1992-02-06
Abstract: Abstract of the Disclosure Disclosed is a method of rapidly checking surfaces for the presence of traces of specific compounds such as certain explosives and drugs.  A hand-covering such as a cotton glove is used to wipe surfaces to pick up particles of the specific compound which may indicate the presence of larger amounts or previous contact of a surface by a person who has handled the compound.  The particles are transferred - unheated - to collection surfaces of a hand-held sample probe by vacuuming of the gloved hand by the battery-operated probe.  Heat is then supplied by a source external to the probe to vaporize the particles, and the vapors are analyzed by a suitable technique such as high speed gas chromatography.  The method permits checking of surfaces for explosives at processing rates of up to several samples per minute.     3688d

Abstract: A duplicated transmission system in which two optical wavelengths are utilized on each of a pair of optical links with one optical wavelength communicating data and the other optical wavelength communicating a signal designating an active optical link of the pair. Each of the optical links is terminated on a transmit unit and a receive unit. The two transmit units determine which of the optical links is the active optical link, and each of the transmit units then transmits a signal on the second wavelength of the terminated optical link indicating this decision. The second wavelength of the active optical link designates that it isactive, and the second wavelength of the standby optical link designates that it is the standby optical link. Upon reception of the information on the second wavelengths, the receive units both select the active optical link.
